Find the value of x, rounded to the nearest tenth.

Mathematics
1 answer:
german3 years ago

Answer:

25.8

Step-by-step explanation:

We use the segment of secants theorem to find x. The theorem states that the product of the lengths of one secant segment and its external segment equals the product of the lengths of the other secant segment and its external segment. That means (a+b)b=(c+d)d. Then we simply plug in the numbers: (x+5)5=(15+7)7. Then solve for x by simplifying (x+5)5= 154, divide by 5 on both sides, x+5= 30.8, and subtract 5 from both sides, x= 25.8.

Step-by-step explanation:

8.  log_{10}(2.15)   = 0.332 \: then \:   log_{10}(21500)   = ..... \\  log(21500)  =  log(2.15 \times 10000)  \\   =  log(2.15)  +  log(10000)  \\   = log_{10}(2.15)  +  log_{10}( {10}^{4} )  \\  = 0.332 + 4 log_{10}(10)  \\  = 0.332 + 4(1) \\  log_{10}(21500)  = 4.332

9. log(2)=a, log(3)=b, then log(36)=______

log(36) = log(6*6) = log(6) + log(6)

log(36)= log(6) + log(6)

log(36) = log(3*2) + log(3*2)

log(36) = (log(3) + log(2)) + (log(3) + log(2))

log(36) = (a + b) + (b + a)

log(36) = a + b + b + a

log(36) = 2a + 2b

Which graph shows the solution to the system of linear inequalities?
Brilliant_brown [7]

Answer:

this is answer

Step-by-step explanation:

To graph a linear inequality in two variables (say, x and y ), first get y alone on one side. Then consider the related equation obtained by changing the inequality sign to an equality sign. The graph of this equation is a line. If the inequality is strict ( < or > ), graph a dashed line.
